> How can I create seperate indices for each random directory?

That's simple enough. Parse [log][file][path] using grok to extract the directory name (e.g. see [this](https://discuss.elastic.co/t/is-it-possible-to-create-multiple-index-with-multiple-folder-name/321457/2) thread).

However, creating an index per day per directory can be a performance issue in elasticsearch because it can create a large number of small indexes/shards. (An index is stored in one or more shards.)

The [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/size-your-shards.html) recommends using multi-gigabyte shards.
